Make a default logger and mapper in a .h file to be used by examples
Remove logger and mapper from libs
Make method to set the default mapper for the debug methods
Remove port properties and replace them with port params. Move the
params from the PortInfo to enum_params.
Use the Param ranges to specify possible sizes etc.
Improve event and command init so that it can be used more easily
as compound literals.
Improve volume
Make it possible to use graph scheduler in test-mixer
Use an incremented variable to support all resolutions. If the width of
the pludge part of the test image was not dividable by three, a
rounding error made the resulting pattern containing noise.
Use dynamic types for the data and meta types.
Move the meta into a separate header.
Remove port state, we can keep track of that ourselves.
Add size to MetaDataEnable params
Use absolute indexes that we let wrap around. We can then easily detect
how much we under of overflowed by using serial number arithmetic.
Remove the Areas, we can trivially compute this ourselves, move the
logic in read/write_data.
In pull mode, schedule all upstream nodes first, if any of them
produce output, push it into the current node.
Underrun streams without input on audiomixer, avoids glitch when
starting a new stream.
Remove the node state. The state of the node is based on the state
of the ports, which can be derived directly from calling the port
methods. Track this state in the Port instead.
Add a mixer module that puts a mixer in from of audio sinks. This allows
multiple clients to play on one sink (still has some bugs). do some
fixes in the mixer and the scheduler to make this work.
Unify input and output io areas.
Add support for ranges in the io area.
Automatically recycle buffers in the output areas in process_output
Improve the mixer, add use_buffer support, use a queue of input buffers,
fix mixing, add support for ranges.
Fix mixer and v4l2 tests
